Description

  The present invention relates to a coin dispensing device, a coin dispensing method, and a coin dispensing program, and is suitable for application to a cash register change machine used in a checkout office of a retail store such as a supermarket or a convenience store.

  2. Description of the Related Art In recent years, cash register change machines in which a cash register processing unit that performs deposit / withdrawal processing of banknotes and coins as a medium is becoming widespread in a register unit connected to a POS (Point Of Sales) system or the like.

  Among these cash register change machines, there are also proposed ones in which a change amount is calculated in the checkout process and a change and a number of bills and coins according to the change amount are discharged by the change processing unit (for example, , See Patent Document 1).

  For example, in a cashier change machine, when a customer purchases a product at a retail store, the cashier pays the cash paid for the product from the customer. The cashier then inserts the cash into the cashier change machine, so that the cashier change machine recognizes the amount of money inserted and calculates the change amount.

  Subsequently, the cash register changer determines the denomination and the number of bills and coins according to the change amount by the change processing unit. And the cash register change machine makes the cashier take out the banknotes and coins of the determined denomination and the number of banknotes and coins and deliver them to the customer.

JP 2010-152436 A (FIG. 1)

  In the cash register change machine having such a configuration, when a coin is withdrawn, the entire change amount is withdrawn in a lump, and this is taken out by a cashier and handed over to the customer. At this time, the customer may want to confirm whether or not the handed coin matches the change amount.

  However, when there are many coin types and number of coins, it is not easy for customers who have been handed coins to immediately check the amount of coins that are mixed in multiple types, that is, the type and number of coins. There was a problem that it might take time.

  The present invention has been made in consideration of the above points, and intends to propose a coin dispensing apparatus, a coin dispensing method, and a coin dispensing program that can easily confirm the type and number of dispensed coins. It is.

  In order to solve such a problem, in the coin dispensing apparatus, coin dispensing method and coin dispensing program of the present invention, the amount to be withdrawn is displayed on a predetermined display unit, and based on the amount to be withdrawn Withdrawal instructions to determine the number of coins for each denomination, select some of the withdrawal amounts as target digits, and withdraw the corresponding number of coins of the corresponding denomination for each target digit By making the specified withdrawal part, the designated number of coins is withdrawn by the designated number, and the coin is withdrawn from the withdrawal part and displayed on the display part. The display contents of the display unit are controlled so that the display method of the target digit or the vicinity thereof in the amount of withdrawals is different from other digits.

  Since the present invention dispenses coins for each target digit, the denomination and the number of the coins can be easily confirmed for each target digit, and the amount of money of the target digit at that time can be easily visually recognized by the display unit. be able to. Therefore, according to the present invention, it is possible to immediately confirm that the amount of coins actually withdrawn matches the amount withdrawn.

  According to the present invention, since coins are withdrawn for each target digit, the denomination and the number of pieces can be easily confirmed for each target digit, and the withdrawal amount of the target digit at that time can be easily displayed on the display unit. Since it can be visually recognized, it can be immediately confirmed that the amount of coins actually withdrawn coincides with the amount of withdrawal. Thus, the present invention can realize a coin dispensing apparatus, a coin dispensing method, and a coin dispensing program that can easily confirm the type and number of dispensed coins.

  Hereinafter, modes for carrying out the invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

[1. First Embodiment]
[1-1. Structure of cash register change machine]
As shown in FIG. 1, the cash register change machine 1 is roughly composed of an upper register unit 2 and a lower change processing unit 3. The cashier change machine 1 is operated by a cashier when a customer pays for a product he / she wants to purchase at a checkout (a so-called cash register) of a retail store such as a supermarket or a convenience store.

  In the following description, the side face facing the cashier and the opposite face are defined as the front face and the rear face, respectively, and the left and right and top and bottom are defined as viewed from the cashier.

  The register unit 2 is configured to control the entire cashier change machine 1 by a built-in integrated control unit 5. Further, a bar code reader (not shown) is connected to the register unit 2, and the bar code attached to the merchandise is read by the bar code reader so as to recognize the merchandise.

  The display operation unit 6 includes a display unit 6A made up of a liquid crystal display or the like and an operation unit 6B made up of a touch panel or the like placed on the liquid crystal display.

  The display operation unit 6 displays the name and price of the recognized product on the liquid crystal display. The display operation unit 6 displays input keys such as numbers on a part of the display screen. When a position corresponding to the input key on the touch panel is pressed, the input operation corresponding to the input key is accepted. To the overall control unit 5. In response to this, the overall control unit 5 performs various processes such as increase / decrease in the quantity of goods and correction of the amount of money.

  The register unit 2 includes a receipt processing unit 7. The receipt processing unit 7 prints the name, amount, etc. of the recognized product on the receipt and discharges it from the receipt discharge port 7A.

  On the other hand, the change processing unit 3 is roughly divided into a left coin processing unit 11, a right banknote processing unit 12, and a front upper operation unit 13.

  On the front surface of the coin processing unit 11, a coin depositing port 14 is provided in the upper stage, and a reject port 15 and a coin dispensing port 16 are provided below the coin depositing port 14.

  The coin depositing port 14 is formed in a shape that is shaped like a mortar, and a taking-in mechanism for taking in coins one by one is built into the bottom thereof. In addition, a sensor (not shown) for detecting the presence or absence of coins is incorporated in the coin deposit port 14 at a predetermined location.

  Each of the reject port 15 and the coin dispensing port 16 protrudes forward from the lower front portion of the coin processing unit 11 and has a shape in which the upper center is respectively punched in a bowl shape. The coin dispensing port 16 also incorporates a sensor 16S that detects the presence or absence of coins at a predetermined location. Further, behind the coin dispensing port 16, a dispensing unit 17 for dispensing coins of the denomination designated by the change control unit 21 described later is provided.

  On the front surface of the banknote processing unit 12, a banknote deposit / withdrawal port 18 for taking in banknotes from the outside and discharging the banknotes to the outside is provided. Behind the banknote deposit / withdrawal port 18 is built in a withdrawal unit 19 for dispensing the designated number of banknotes instructed by the change control unit 21 described later.

  The operation unit 13 includes a combination of a display panel in which an LED (Light Emitting Diode) or the like is incorporated and a plurality of operation buttons.

  The display panel of the operation unit 13 is configured to display the operation status in the coin processing unit 11 and the banknote processing unit 12. For example, the coin processing unit 11 has insufficient coins for change or is abnormal inside. Is detected, or the location thereof is displayed.

  The operation button of the operation unit 13 is configured to accept an instruction relating to, for example, the transfer of coins through a pressing operation by a cashier or the like.

  Further, a change control unit 21 is provided inside the change processing unit 3. As shown in the block configuration of FIG. 2, the change control unit 21 is configured around a CPU (Central Processing Unit) 22, and reads various programs such as a change withdrawal program from a memory 23 such as a flash memory. By executing this, the change processing unit 3 is controlled in an integrated manner.

  The CPU 22 of the change control unit 21 is connected to a plurality of motors, solenoids, and sensors incorporated in the coin processing unit 11 and the banknote processing unit 12 via I / O (Input / Output) ports 24 and 25, respectively. The operation switch and the display panel of the operation unit 13 are connected to each other via the I / O port 26.

  Further, the CPU 22 of the change control unit 21 is also connected to the CPU 31 of the overall control unit 5 incorporated in the register unit 2 so as to execute various processes in cooperation with each other. Incidentally, the CPU 31 of the overall control unit 5 reads the various programs from the memory 32 and executes them to control the register unit 2 and the cash register changer 1 as a whole.

  In the actual settlement process, the overall control unit 5 executes a predetermined settlement process program and causes the change control unit 21 to execute a predetermined deposit program.

  For example, when a cashier deposits banknotes and coins as a product price from a customer, the banknotes are inserted into the banknote deposit / withdrawal port 17 (FIG. 1) by the cashier, and the coins are put together by the cashier to the coin deposit port 14 (FIG. 1). ).

  When detecting that the coin has been inserted by the sensor, the coin deposit port 14 takes in the coins one by one based on the control of the change control unit 21 and transfers it to a coin discrimination unit (not shown).

  The change control unit 21 discriminates coin denominations (for example, 6 types of 1 yen, 5 yen, 10 yen, 50 yen, 100 yen and 500 yen) and authenticity by the coin discrimination part, and if it is abnormal, the change The coin is discharged from the reject port 15, and if it is normal, the coin is stored in a storage (not shown) for each denomination.

  Further, the change control unit 21 discriminates the denominations and authenticity of banknotes one by one by the banknote processing unit 12 and stores them in an internal storage (not shown).

  Here, the change control unit 21 calculates the amount of money received and notifies the overall control unit 5. In response to this, the overall control unit 5 calculates the change amount CH by subtracting the price of the product from the deposit amount, notifies the change control unit 21 and causes the change control unit 21 to execute the change dispensing program.

  As shown in FIG. 3A, the change control unit 21 provides a change display column CC in the lower right part of the display operation unit 6, and then changes the change amount CH with a relatively large number in the change display column CC. Is displayed. In the change display column CC, the size of the numbers, the color scheme, and the like are appropriately determined so that the cashier can easily see the change and the customer can easily see the change.

  In addition, the change control unit 21 causes the banknote corresponding to the change amount CH to be withdrawn from the banknote deposit / withdrawal port 18, and causes the coin according to the change amount to be withdrawn from the internal storage by the withdrawal unit 17. 16 is withdrawn (details will be described later).

  In response to this, the cashier gives the customer the bills and coins as change together with the receipt printed with the receipt processing unit 7 (FIG. 1), thereby completing a series of settlement processing.

[1-2. Change payment processing]
By the way, in the change processing unit 3, when the coins are particularly withdrawn from the change, the whole amount is not withdrawn all at once, but is withdrawn separately for each digit. Here, the change dispensing process in which the change processing unit 3 withdraws banknotes and coins corresponding to the change amount CH as change will be described in detail.

  When performing the change dispensing process, the change control unit 21 reads a change dispensing program from the memory 23 and executes it in the CPU 22. As a result, the change control unit 21 constitutes functional blocks such as a number determination unit 41, a digit selection unit 42, a withdrawal instruction unit 43, and a display control unit 44, as shown in FIG.

  When receiving the change amount CH notification from the overall control unit 5, the sheet number determination unit 41 determines the number of banknotes and coins to be withdrawn according to the amount for each denomination, and this is determined by the digit selection unit 42 and the withdrawal unit. Supply to the gold instruction unit 43.

  The digit selection unit 42 disassembles the unpaid amount of the change amount CH (hereinafter referred to as the remaining amount) for each digit, and then sets the largest digit of the remaining amount to be withdrawn (hereinafter referred to as the withdrawal target). This is called the target digit DG) and notified to the withdrawal instruction unit 43.

  The withdrawal instruction unit 43 generates a withdrawal instruction for withdrawing the number of coins or coins of the denomination corresponding to the target digit DG by the number determined by the number determination unit 41, and sends this to the withdrawal unit 17 or 19. Supply. In response to this, the withdrawal units 17 and 19 dispense the specified number of banknotes or coins instructed by the withdrawal instruction.

  The display control unit 44 displays a change amount CH in the change display column CC (FIG. 3A) in the display screen by supplying a display command to the display unit 6A of the display operation unit 6 (FIG. 1). The display is changed according to the target digit DG.

  And the change control part 21 is made to withdraw change by performing each process by each functional block sequentially according to the change dispensing process procedure RT1 shown in FIG.

  That is, the change control unit 21 starts the change dispensing process procedure RT1 when executing the change dispensing program, and proceeds to step SP1. In step SP1, the change control unit 21 acquires the change amount CH from the overall control unit 5, supplies it to the number determination unit 41 and the display control unit 44 (FIG. 4), and proceeds to the next step SP2.

  In step SP2, the change control unit 21 supplies a predetermined display command from the display control unit 44 (FIG. 4) to the display unit 6A (FIG. 4) of the display operation unit 6 (FIG. 1), thereby changing the change in the display screen. The change amount CH is displayed in the display column CC (FIG. 3A), and the process proceeds to the next step SP3. Incidentally, the change amount CH is displayed by a black number on a white background, for example.

  In step SP3, the change control unit 21 sets the same value as the change amount CH as the initial value of the remaining amount, and proceeds to the next step SP3.

  In step SP4, the change control unit 21 determines the number of banknotes and coins to be withdrawn as change by the number determination unit 41 (FIG. 4), and uses this to determine the digit selection unit 42 and the withdrawal instruction unit 43. To move to the next step SP4.

  In step SP5, the change control unit 21 determines whether or not the bill should be withdrawn as change, in other words, whether or not the change amount CH is 1000 yen or more. If a positive result is obtained here, the change control unit 21 proceeds to the next step SP5.

  In step SP6, the change control unit 21 supplies a withdrawal instruction of banknotes from the withdrawal instruction unit 43 to the withdrawal unit 19, thereby dispensing a 1000-digit digit portion of the change amount CH. Move to SP7.

  In step SP7, the change control unit 21 updates the remaining amount by subtracting the amount of money already withdrawn from the remaining amount, and proceeds to the next step SP8.

  On the other hand, if a negative result is obtained in step SP5, this means that it is not necessary to withdraw the banknote as change, and the banknote control unit 21 moves to the next step SP8.

  In step SP8, the change control unit 21 determines whether or not the remaining amount is greater than 0, in other words, whether or not it is necessary to withdraw coins as change. If a positive result is obtained here, the change control unit 21 proceeds to the next step SP9 and performs a coin dispensing process.

  In step SP9, the change control unit 21 starts a coin dispensing subroutine SRT1 shown in FIG. 6, and moves the process to step SP11.

  In step SP11, the change control unit 21 uses the digit selection unit 42 (FIG. 4) to select the largest digit of the remaining amount as the target digit DG, and notifies this to the withdrawal instruction unit 43 and the display control unit 44. Control goes to the next step SP12.

  In step SP12, the change control unit 21 causes the display control unit 44 to change the color of the target digit DG in the change amount CH displayed in the change display column CC in the display screen, for example, as shown in FIG. The color is changed to a color different from other digits (for example, red), and the process proceeds to the next step SP13.

  In step SP13, the change control unit 21 uses the withdrawal instruction unit 43 to generate a withdrawal instruction for dispensing only the coins of the target digit DG, supplies this to the withdrawal unit 17, and then proceeds to the next step SP14. .

  In response to this, the withdrawal unit 17 dispenses only the coins of the target digit DG to the coin withdrawal port 16 (FIG. 1) in accordance with the withdrawal instruction. At this time, the cashier takes out the coins withdrawn from the coin dispensing slot 16 while referring to the change display column CC of the display unit 6A, and returns it to the customer.

  In step SP14, the change control unit 21 updates the remaining amount by subtracting the amount of money already withdrawn from the remaining amount, and proceeds to the next step SP15.

  In step SP15, the change control unit 21 uses the digit selection unit 42 to determine whether or not the remaining amount is greater than 0, that is, whether or not there is a coin that has not yet been withdrawn from the change. If a positive result is obtained here, the change control unit 21 proceeds to the next step SP16.

  In step SP16, the change control unit 21 determines whether or not a coin has been taken out from the coin dispensing port 16 based on whether or not the digit selection unit 42 has acquired a detection signal from the sensor 16S of the coin dispensing port 16. judge. If a negative result is obtained here, the change control unit 21 waits for a coin to be taken out from the coin dispensing port 16 by repeating this step SP15.

  On the other hand, if a positive result is obtained in step SP16, the change control unit 21 returns to step SP11 again and repeats a series of processes in order to perform the withdrawal process after selecting the next target digit DG.

  If a negative result is obtained in step SP15, this indicates that all of the change amount CH has been withdrawn, and at this time, the change control unit 21 proceeds to the next step SP17.

  In step SP17, the change control unit 21 ends the coin withdrawal subroutine SRT1, returns the process to the original change withdrawal processing procedure RT1 (FIG. 5), moves to the next step SP10, and ends the change withdrawal processing procedure RT1. To do.

  Further, when a negative result is obtained in step SP8, that is, when there is no need to dispense coins as change, the change control unit 21 proceeds to step SP10 and ends the change dispensing process procedure RT1.

  In this way, the change control unit 21 sequentially changes the target digit DG while dispensing the change coins one digit at a time, and changes the display color of the target digit DG in the change display column CC to a color different from the other digits. It has been made to change.

[1-3. Change withdrawal sequence]
Next, the relationship among the withdrawal process from the change processing unit 3, the display of the change display column CC, and the refund to the customer by the cashier will be described along the time series using the sequence chart of FIG. Here, as an example, it is assumed that the change amount CH is “3777 yen”.

  The change processing unit 3 first sets the number of denominations based on the change amount CH as “1000 yen bills, 500 yen coins, 1 100 yen coins, 50 yen coins, 10 2 yen coins, 1 5 yen coin, and 2 1 yen coins ”. Further, the change processing unit 3 displays the change amount CH in the change display column CC with a normal number (black), and sets the initial value of the remaining amount to “3777 yen” which is the same as the change amount CH.

  And since the change amount CH is 1000 yen or more in the sequence Q1, the change processing unit 3 causes the withdrawal unit 19 to withdraw three 1000 yen bills according to the 1000 yen digit of the change amount CH, and the remaining amount Is updated to “777 yen”. At this time, the change display column CC still displays all the digits of the change amount CH as normal numbers.

  In response to this, the cashier gives a refund of 3000 yen taken out from the banknote deposit / withdrawal port 18 while explaining, for example, “I will return 3000 yen from the largest one”.

  Next, the change processing unit 3 sets the 100-digit digit, which is the largest digit of the remaining amount “777 yen”, as the target digit DG in the sequence Q2, and includes the change amount CH displayed in the change display column CC. The display color of the 100-digit digit that is the target digit DG is changed from black to red. At the same time, the change processing unit 3 causes the denomination corresponding to the target digit DG, “one 500 yen coin and two 100 yen coins”, to be withdrawn from the withdrawal unit 17 and updates the remaining amount to “77 yen”. .

  In response to this, the cashier refers to the 100-yen digit whose display color is changing in the change display column CC and explains, for example, “I will return 700 yen next”. Refund the customer with 700 yen taken from

  When the change processing unit 3 detects that the coin has been taken out from the coin dispensing port 16 by the sensor 16S, the change processing unit 3 proceeds to the next sequence Q3.

  In the sequence Q3, the change processing unit 3 sets the 10-digit digit, which is the largest digit of the remaining amount “77 yen”, as the target digit DG, and the change amount CH displayed immediately before the change amount CH displayed in the change display column CC. The display color of the 100-yen digit that is the target digit DG is returned to black, and the display color of the 10-yen digit that is the current target digit DG is changed from black to red. At the same time, the change processing unit 3 causes the denomination corresponding to the target digit DG, “one 50 yen coin and two 10 yen coins”, to be withdrawn from the withdrawal unit 17 and updates the remaining amount to “7 yen”. .

  In response to this, the cashier refers to the 10-yen digit whose display color is changing in the change display column CC and explains, for example, “I will give you 70 yen next”. Refund the customer for 70 yen.

  When the change processing unit 3 detects that the coin has been taken out from the coin dispensing port 16 by the sensor 16S, the change processing unit 3 proceeds to the next sequence Q4.

  In the sequence Q4, the change processing unit 3 sets the 1-digit digit, which is the largest digit of the remaining amount of “7 yen”, as the target digit DG, and the change amount CH displayed immediately before the change amount CH displayed in the change display column CC. The display color of the 10-yen digit that is the target digit DG is returned to black, and the display color of the 1-yen digit that is the current target digit DG is changed from black to red. At the same time, the change processing unit 3 causes the withdrawal unit 17 to withdraw “one 5-yen coin and two 1-yen coins”, which is a denomination corresponding to the target digit DG, and updates the remaining amount to “0 yen”. .

  In response to this, the cashier refers to the 1-yen digit whose display color is changing in the change display column CC and explains, for example, “I will return the remaining 7 yen”, etc. Refund 7 yen taken out from

  Incidentally, since the remaining amount is “0 yen”, the change processing unit 3 ends the series of withdrawal processing by this sequence Q4.

[1-4. Operation and effect]
In the above configuration, when the change control unit 21 according to the first embodiment receives notification of the change amount CH from the overall control unit 5, the change amount CH is displayed in the change display column CC, and the change amount CH The number of banknotes and coins to be withdrawn is determined for each denomination. If the change amount CH is 1000 yen or more, the change control unit 21 first withdraws the banknote and updates the remaining amount.

  At this time, for example, the cashier can clearly indicate to the customer that he has handed out 3000 yen, which is a digit of 1000 yen, out of the change amount CH by counting 1000 yen bills one by one in front of the customer.

  Subsequently, the change control unit 21 sets the target digit DG to the maximum digit of the remaining amount, changes the display color of the target digit DG in the change amount CH displayed in the change display column CC, and Withdraw coins of denomination of digit DG only.

  In other words, the change control unit 21 divides the portion of the change amount CH from which coins are to be dispensed into each digit, and dispenses while changing the display of the change display column CC to emphasize it temporarily.

  For this reason, the change control unit 21 sets the types of coins to be dispensed to the coin dispensing port 16 within two types (500 yen coins, 100 yen coins, etc.) and the number of coins within 5 (900 yen, etc.). can do.

  As a result, the change control unit 21 makes it easy for the customer to select the type and number of coins when the cashier takes out the coins from the coin dispensing port 16 or when the cashier hands the coins to the customer. It can be grasped and the burden can be reduced.

  At this time, the change control unit 21 changes the withdrawal digit (that is, the target digit DG) to a color different from that of the other digits, so the amount of the digit being withdrawn from the change amount CH (700 yen or 70 yen etc.) can be immediately recognized by cashiers and customers, and can be easily compared with the total amount of coins actually withdrawn.

  In addition, the change control unit 21 displays the full change amount CH in the change display column CC and changes the color of the target digit DG from that of the other digits. It is possible to recognize at a glance the progress status such as whether the money has been paid and which part has not been withdrawn.

  By the way, in addition to handing it to the customer every time coins are withdrawn, the cashier takes out with one hand each time coins are withdrawn, shows it to the customer and holds it in the other hand. In addition, after all the coins have been withdrawn, all the coins held in the other hand may be collectively delivered to the customer.

  Further, the change control unit 21 moves the target digit DG to the next digit after detecting by the sensor 16S that the coin dispensed to the coin dispensing port 16 has been taken out by the cashier. For this reason, the change control unit 21 also performs the following when the time until the coin is taken out from the coin dispensing port 16 is prolonged, for example, when the cashier receives a question from the customer during the change dispensing process. Refunds can be made sequentially for each digit without mixing coins of the target digit DG.

  According to the above configuration, the change control unit 21 changes the display color of the target digit DG in the change amount CH displayed in the change display column CC while sequentially moving the target digit DG, and the target digit DG. Withdraw coins of DG denomination only. As a result, the change control unit 21 can suppress both the type and number of coins to be dispensed to the coin dispensing port 16 at a time while temporarily changing and emphasizing the display of the change display column CC. , Cashiers and customers can easily grasp the type and number of coins withdrawn for each target digit DG, and easily match the target digit DG of the numbers displayed in the change display column CC Can be made.

[2. Second Embodiment]
In the second embodiment, a change control unit 121 is used instead of the change control unit 21 according to the first embodiment.

[2-1. Change payment processing]
The change control unit 121 divides money into each digit according to the total number of coins to be withdrawn, or withdraws all digits at once, particularly when coins are withdrawn from the change. It is made to switch.

  Specifically, the change control unit 121 has the same circuit configuration as the change control unit 21 according to the first embodiment (FIG. 2), but when the change dispensing program is executed, Differently, a functional block as shown in FIG. 8 is configured by assigning the same reference numerals to those corresponding to FIG.

  That is, the change control unit 121 corresponds to the digit selection unit 42 and the display control unit 44 according to the first embodiment, in addition to the number determination unit 41 and the withdrawal instruction unit 43 similar to those of the first embodiment. A digit selection unit 142 and a display control unit 144 are provided, and a total number calculation unit 145 and a timing unit 146 are further provided.

  As with the display control unit 44, the display control unit 144 displays the change amount CH in the change display column CC (FIG. 3A) in the display screen (ie, displays black numbers on a white background), as shown in FIG. In this way, the color of the target digit DG is inverted (that is, displayed with white numerals on a black background).

  The total number calculation unit 145 calculates the total number of coins to be withdrawn by adding all the number of coins of the denomination determined by the number determination unit 41, and supplies this to the digit selection unit 142.

  The digit selection unit 142 compares the total number supplied from the total number calculation unit 145 with a predetermined threshold (for example, 10), and if the total number is equal to or greater than the threshold, either one digit of the change amount CH, If the total number is less than the threshold value, all the digits (that is, a maximum of three digits) to be dispensed with coins out of the change amount CH are respectively selected as the target digits DG.

  The time measuring unit 146 measures time and notifies the digit selecting unit 142 of the time.

  The change control unit 121 dispenses change according to the change dispensing process procedure RT1 (FIG. 5) as in the first embodiment, but the coin dispensing process at step SP9 corresponds to FIG. A coin dispensing subroutine SRT2 shown in FIG. 10 is executed.

  That is, the change control unit 121 starts the coin dispensing subroutine SRT2, moves to step SP21, and calculates the total number by adding all the number of coins of all denominations corresponding to the remaining amount by the total number calculating unit 145, Control goes to the next step SP22.

  In step SP22, the change control unit 121 determines whether the total number of sheets is less than a threshold (for example, 10 sheets) by using the digit selection unit 142. If a positive result is obtained here, this means that the total number of coins to be withdrawn is relatively small, and it is not difficult to grasp the denomination and number of coins even if they are withdrawn in a lump. At this time, the change control unit 121 proceeds to the next step SP23.

  In step SP23, the change control unit 121 uses the digit selection unit 142 to select all digits (up to three digits) corresponding to the balance as the target digits DG, and proceeds to the next step SP24.

  In step SP24, the change control unit 121 causes the display control unit 144 to invert the color of the target digit DG in the change amount CH displayed in the change display column CC in the display screen, and proceeds to the next step SP25.

  In step SP25, the change control unit 121 generates a withdrawal instruction for dispensing the coins of the target digit DG, that is, all the remaining coins, by the withdrawal instruction unit 43, and supplies the withdrawal instruction to the withdrawal unit 17 after that. The process proceeds to step SP26.

  In response to this, the withdrawal unit 17 dispenses the coin of the target digit DG to the coin dispensing port 16 (FIG. 1) in accordance with the withdrawal instruction. At this time, the cashier takes out the coins withdrawn from the coin dispensing slot 16 while referring to the change display column CC of the display unit 6A, and returns it to the customer.

  In step SP26, the change control unit 121 updates the remaining amount to “0” by subtracting the amount of money paid out from the remaining amount, and proceeds to the next step SP33.

  On the other hand, if a negative result is obtained in step SP22, this means that the total number of coins to be withdrawn is relatively large, and it is not easy to grasp the denomination and number of coins if they are withdrawn in a lump. At this time, the change control unit 121 proceeds to the next step SP27.

  In step SP27, the change control unit 121 uses the digit selection unit 142 to select the largest digit of the remaining amount as the target digit DG, notifies the withdrawal instruction unit 43 and the display control unit 144 of this, and performs the next step SP28. Move on.

  In step SP28, the change control unit 121 causes the display control unit 144 to invert the color of the target digit DG in the change amount CH displayed in the change display column CC in the display screen, and proceeds to the next step SP29.

  In step SP29, the change control unit 121 generates a withdrawal instruction for dispensing only the coins of the target digit DG by using the withdrawal instruction unit 43, supplies this to the withdrawal unit 17, and then proceeds to the next step SP30. .

  In response to this, the withdrawal unit 17 dispenses only the coins of the target digit DG to the coin withdrawal port 16 (FIG. 1) in accordance with the withdrawal instruction. At this time, the cashier takes out the coins withdrawn from the coin dispensing slot 16 while referring to the change display column CC of the display unit 6A, and returns it to the customer.

  In step SP30, the change control unit 121 updates the remaining amount by subtracting the amount of money already withdrawn from the remaining amount, and proceeds to the next step SP31.

  In step SP31, the change control unit 121 uses the digit selection unit 142 to determine whether or not the remaining amount is greater than 0, that is, whether or not there is a coin that has not yet been withdrawn from the change. If a positive result is obtained here, the change control unit 121 proceeds to the next step SP32.

  In step SP32, the change control unit 121 uses the time measuring unit 146 to determine whether or not a predetermined standby time (for example, 5 seconds) has elapsed since the coin was dispensed. If a negative result is obtained here, the change control unit 121 waits for the standby time to elapse by repeating this step SP32.

  On the other hand, if an affirmative result is obtained in step SP32, this means that a sufficient time has passed since the coin of the target digit DG has been withdrawn immediately before, and the coin has already been taken out from the coin dispensing port 16. This indicates that there is a high possibility that the coin of the next target digit DG should be withdrawn. At this time, the change control unit 121 returns to step SP27 and repeats a series of processes.

  If a negative result is obtained in step SP31, this indicates that all of the change amount CH has been withdrawn, and at this time, the change control unit 121 proceeds to the next step SP33.

  In step SP33, the change control unit 121 ends the coin withdrawal subroutine SRT2 and returns the process to the original change withdrawal processing procedure RT1 (FIG. 5).

  As described above, the change control unit 121 selects and withdraws all or one digit of the remaining amount as the target digit DG according to the total number of coins to be withdrawn as change, and the target digit in the change display column CC. The display of DG is reversed.

[2-2. Change withdrawal sequence]
Next, regarding the relationship between the withdrawal process from the change processing unit 3, the display of the change display column CC, and the refund to the customer by the cashier, using the sequence charts of FIGS. 11 and 12 corresponding to FIG. explain.

[2-2-1. When withdrawing all at once]
First, as an example, FIG. 11 shows a case where the change amount CH is assumed to be “3333 yen”. The change processing unit 3 determines that the number of denominations based on the change amount CH is “three 1000 yen bills, three 100 yen coins, three 10 yen coins, and three 1 yen coins”. decide. Further, the change processing unit 3 displays the change amount CH in the change display column CC with a normal number (black), and sets the initial value of the remaining amount to “3333 yen” which is the same as the change amount CH.

  And since the change amount CH is 1000 yen or more in the sequence Q11, the change processing unit 3 causes the withdrawal unit 19 to withdraw three 1000 yen bills according to the 1000 yen digit of the change amount CH, and the remaining amount Is updated to “333 yen”. At this time, in the change display column CC, the display content is not particularly changed while all digits are displayed as normal numbers.

  In response to this, the cashier gives a refund of 3000 yen taken out from the banknote deposit / withdrawal port 18 while explaining, for example, “I will return 3000 yen from the largest one”.

  Next, the change processing unit 3 calculates the total number in the case of withdrawing “333 yen” as the remaining amount as “9” in sequence Q12, and this is less than the threshold value of 10 sheets. The digit is the target digit DG, and the three-digit display of 100 yen, 10 yen, and 1 yen, which is the target digit DG, of the change amount CH displayed in the change display column CC is reversed.

  At the same time, the change processing unit 3 causes the withdrawal unit 17 to withdraw “3 100 yen coins, 3 10 yen coins and 3 1 yen coins”, which are denominations corresponding to the target digit DG, The remaining amount is updated to “0 yen” and a series of withdrawal processing is completed.

  In response to this, the cashier refers to the 100 yen, 10 yen, and 1 yen digits that are highlighted in the change display column CC, and explains, for example, “I will return the remaining 333 yen”. 333 yen taken out from the coin outlet 16 is returned to the customer.

  Incidentally, since the remaining amount is "0 yen", the change processing unit 3 ends the series of withdrawal processing by this sequence Q12.

[2-2-2. When withdrawing money by digit]
Next, as another example, FIG. 12 shows a case where the change amount CH is assumed to be “3334 yen”. The change processing unit 3 determines that the number of denominations based on the change amount CH is “three 1000 yen bills, three 100 yen coins, three 10 yen coins, and four 1 yen coins”. decide. Further, the change processing unit 3 displays the change amount CH in the change display column CC with a normal number (black), and sets the initial value of the remaining amount to “3334 yen” which is the same as the change amount CH.

  And since the change amount CH is 1000 yen or more in the sequence Q21, the change processing unit 3 causes the withdrawal unit 19 to withdraw three 1000 yen bills according to the 1000 yen digit of the change amount CH, and the remaining amount Is updated to “334 yen”. At this time, in the change display column CC, the display content is not particularly changed while all digits are displayed as normal numbers.

  In response to this, the cashier gives a refund of 3000 yen taken out from the banknote deposit / withdrawal port 18 while explaining, for example, “I will return 3000 yen from the largest one”.

  Next, the change processing unit 3 calculates the total number in the case of withdrawing the remaining amount of “334 yen” as “10” in the sequence Q22, and this is the threshold value of 10 or more. The digit of 100 yen, which is a digit, is set as the target digit DG, and the display of the digit of 100 yen, which is the target digit DG, of the change amount CH displayed in the change display column CC is reversed. At the same time, the change processing unit 3 causes the withdrawal unit 17 to withdraw “three 100-yen coins”, which is a denomination corresponding to the target digit DG, and updates the remaining amount to “34 yen”.

  In response to this, the cashier refers to the 100-yen digit whose display is reversed in the change display column CC, and explains, for example, “I will give you 300 yen next”. Refund the removed 300 yen to the customer.

  Here, the change processing unit 3 moves to the next sequence Q23 when 5 seconds, which is a waiting time, has elapsed since the last withdrawal.

  In the sequence Q23, the change processing unit 3 sets the 10-digit digit, which is the largest digit among the remaining amounts of “34 yen”, as the target digit DG, and the change amount CH displayed immediately before the change amount CH displayed in the change display column CC. The display of the 100-yen digit that is the target digit DG is returned to normal, and the display of the 10-yen digit that is the current target digit DG is reversed. At the same time, the change processing unit 3 withdraws “three 10-yen coins”, which is a denomination corresponding to the target digit DG, from the withdrawal unit 17 and updates the remaining amount to “4 yen”.

  In response to this, the cashier refers to the 10-yen digit whose display color is changing in the change display column CC and explains, for example, “I will return 30 yen next”, etc. Refund 30 yen taken out from the customer.

  Here, the change processing unit 3 moves to the next sequence Q24 when 5 seconds, which is a waiting time, has elapsed since the last withdrawal.

  In the sequence Q24, the change processing unit 3 sets the 1-digit digit, which is the largest digit among the remaining amounts of “4 yen” as the target digit DG, and the change amount CH displayed immediately before the change amount CH displayed in the change display column CC. The display of the 10-yen digit that is the target digit DG is returned to normal, and the display of the 1-yen digit that is the current target digit DG is reversed. At the same time, the change processing unit 3 withdraws “four 1-yen coins”, which is a denomination corresponding to the target digit DG, from the withdrawal unit 17 and updates the remaining amount to “0 yen”.

  In response to this, the cashier refers to the 1-yen digit whose display color is changing in the change display column CC and explains, for example, “I will return the remaining 4 yen”, etc. Refund the customer with 4 yen taken from

  Incidentally, since the remaining amount is “0 yen”, the change processing unit 3 ends the series of withdrawal processing by this sequence Q24.

[2-3. Operation and effect]
In the above configuration, when the change control unit 121 according to the second embodiment receives a change amount CH notification from the overall control unit 5, the change amount CH is displayed in the change display column CC, and the change amount CH The number of banknotes and coins to be withdrawn is determined for each denomination. If the change amount CH is 1000 yen or more, the change control unit 121 first withdraws the banknote and updates the remaining amount.

  Subsequently, the change control unit 121 calculates the total number of coins corresponding to the remaining amount. Here, if the total number is less than the threshold value, the change control unit 121 displays the target digit DG in the change amount CH displayed in the change display column CC, with all digits corresponding to the remaining amount as the target digit DG. At the same time, the coins of the target digit DG, that is, all the remaining coins are withdrawn in a lump.

  Further, if the total number of coins corresponding to the balance of the change is equal to or greater than the threshold value, the change control unit 121 sets the target digit DG as the maximum digit of the balance, as in the first embodiment, and displays the change display field. Of the change amount CH displayed on the CC, the display of the target digit DG is reversed and the coin of only the denomination of the target digit DG is withdrawn.

  In other words, the change control unit 121, when the total number of coins of the change amount CH is small, makes it easy for cashiers and customers to grasp the denomination and number of coins. By spending money, the required time can be shortened and labor can be reduced.

  On the other hand, when the total number of coins of the change amount CH is large, the change control unit 121 divides the coins for each digit while extending the required time and increasing labor, It is possible to easily grasp the denomination and number of coins at each withdrawal.

  Furthermore, in order to reverse the display of the target digit DG in the change amount CH displayed in the change display column CC so that the change control unit 121 is linked with the withdrawal of the coin in any case, The customer can easily recognize which part of the change amount is withdrawn.

  Further, when the change control unit 121 makes a withdrawal for each digit, the display of the target digit DG is kept reversed until the waiting time elapses, so that the cashier after withdrawal makes the target digit from the coin dispensing port 16. Until the DG coin is taken out and handed over to the customer, the target digit DG remains inverted.

  Therefore, the change control unit 121 is not only used when the cashier takes out the coin from the coin outlet 16 and confirms it, but when the cashier gives the coin to the customer after that, or after that, the customer displays the change display column CC. Even at the time of comparing with the delivered coin, it is possible to easily focus on the inverted target digit DG.

  In addition, when the change control unit 121 withdraws every digit, when the standby time elapses, the change control unit 121 dispenses the coin of the next digit. Therefore, as in the first embodiment, the change control unit 121 places the sensor 16S in the coin dispensing port 16. There is no need to provide it, which can contribute to simplification of the configuration of the change processing unit 3.

  With respect to other points as well, the change control unit 121 can achieve the same operational effects as the change control unit 21 according to the first embodiment.

  According to the above configuration, the change control unit 121 uses the remaining digits or one digit of the remaining amount as the target digit DG according to the total number of coins to be withdrawn, and the change amount CH displayed in the change display column CC. Among them, the display of the target digit DG is reversed and the coin of only the denomination of the target digit DG is withdrawn. Thereby, the change control unit 121 can suppress both the type and the number of coins to be dispensed to the coin dispensing port 16 at a time while temporarily changing and emphasizing the display of the change display column CC. In addition, when the total number is small, it is possible to withdraw in a lump sum, so that the cashier and customer can easily grasp the type and number of coins withdrawn for each target digit DG, and change display column Of the numbers displayed on the CC, it is possible to easily collate with the portion of the target digit DG. Further, depending on the total number of sheets, the required time can be shortened and labor can be reduced.

[3. Third Embodiment]
In the third embodiment, a change control unit 221 is used instead of the change control unit 21 according to the first embodiment.

[3-1. Change payment processing]
The change control unit 221 is configured to withdraw a plurality of digits for a small number of digits, although the change control unit 221 basically dispenses a coin separately for each digit. Yes.

  Specifically, the change control unit 221 has the same circuit configuration as the change control unit 21 according to the first embodiment (FIG. 2), but when the change dispensing program is executed, Differently, a functional block as shown in FIG. 13 is configured by assigning the same reference numerals to those corresponding to FIG.

  That is, the change control unit 221 corresponds to the digit selection unit 42 and the display control unit 44 according to the first embodiment, in addition to the number determination unit 41 and the withdrawal instruction unit 43 similar to those of the first embodiment. A digit selection unit 242 and a display control unit 244 are provided.

  Similar to the display control unit 44, the display control unit 244 displays the change amount CH as a normal size number in the change display column CC (FIG. 3A) in the display screen, and displays the number of the target digit DG. It is designed to be enlarged.

  The digit selection unit 242 further includes functional blocks of a temporary selection unit 251, a temporary number calculation unit 252, and a comparison selection unit 253.

  The temporary selection unit 251 disassembles the change amount CH for each digit, selects a digit to be temporarily withdrawn in order to select the target digit DG (hereinafter referred to as a temporary target digit DM), To the provisional number calculation unit 252.

  The provisional number calculation unit 252 calculates a provisional number obtained by adding all the numbers of coins of the provisional target digit DM, and notifies the comparison selection unit 253 of this.

  The comparison / selection unit 253 compares the provisional number with a predetermined threshold value (for example, five), and if the provisional number is less than the threshold value, repeats the calculation of the provisional number and the comparison with the threshold value by adding one digit to the provisional target digit, If the provisional number is equal to or greater than the threshold, all provisional target digits DM at this time are selected as the target digits DG.

  The change control unit 221 dispenses change according to the change dispensing process procedure RT1 (FIG. 5) as in the first embodiment, but the coin dispensing process at step SP9 corresponds to FIG. A coin dispensing subroutine SRT3 shown in FIG. 14 is executed.

  That is, the change control unit 221 starts the coin withdrawal subroutine SRT3 and proceeds to step SP41. The temporary selection unit 251 selects the maximum one digit of the remaining amount as the provisional target digit DM, and this to the temporary number calculation unit 252. Notification is made, and the process proceeds to the next step SP42.

  In step SP42, the change control unit 221 calculates the provisional number by adding the number of coins of all provisional target digits DM by the provisional number calculation unit 252, and proceeds to the next step SP43.

  In step SP43, the change control unit 221 determines whether or not the provisional number is equal to or greater than a predetermined threshold (for example, five) by the comparison / selection unit 253. If a negative result is obtained here, this means that the provisional number is relatively small and the number of withdrawals can be increased at the same time. At this time, the change control unit 221 moves to the next step SP44.

  In step SP44, the change control unit 221 adds one digit to the temporary target digit DM by adding the largest digit among the digits not currently selected as the temporary target digit DM to the temporary target digit DM by the temporary selection unit 251. Then, the process proceeds to the next step SP45.

  In step SP45, the change control unit 221 determines whether or not the provisional target digit DM corresponds to all the digits of the balance by the provisional selection unit 251. If a negative result is obtained here, this means that there is still a digit that has not been selected as the temporary target digit DM, so it is necessary to determine again whether another digit can be added to the current temporary target digit DM. At this time, the change control unit 221 returns to step SP42 again.

  On the other hand, if an affirmative result is obtained in step SP45, this indicates that the current temporary target digit DM should be the target digit DG unconditionally because no further temporary target digit DM can be added. At this time, the change control unit 221 moves to the next step SP46.

  If an affirmative result is obtained in step SP43, this indicates that the provisional number is relatively large, so that no more digits should be added to the provisional target digit DM. At this time, the change control unit 221 Control goes to the next step SP46.

  In step SP46, the change control unit 221 uses the comparison / selection unit 253 to select all the current provisional target digits DM as the target digits DG, and proceeds to the next step SP47.

  In step SP47, the change control unit 221 causes the display control unit 244 to display the size of the target digit DG in the change amount CH displayed in the change display column CC in the display screen in a larger size than the other digits. Then, the process proceeds to the next step SP48.

  In step SP48, the change control unit 221 uses the withdrawal instruction unit 43 to generate a withdrawal instruction for dispensing only the coins of the target digit DG, supplies this to the withdrawal unit 17, and then proceeds to the next step SP49. .

  In step SP49, the change control unit 221 updates the remaining amount by subtracting the amount of money already withdrawn from the remaining amount, and proceeds to the next step SP50.

  In step SP50, the change control unit 221 determines whether the remaining amount is larger than 0, that is, whether there is a coin that has not yet been withdrawn from the change, by using the digit selection unit 242. If a positive result is obtained here, the change control unit 221 proceeds to the next step SP51.

  In step SP51, the change control unit 221 acquires a detection signal from the sensor 16S of the coin dispensing port 16 by using the digit selecting unit 242, and determines whether or not a coin has been taken out from the coin dispensing port 16 based on the detection signal. . If a negative result is obtained here, the change control unit 221 waits for the coin to be taken out from the coin dispensing port 16 by repeating this step SP51.

  On the other hand, if a positive result is obtained in step SP51, the change control unit 221 returns to step SP41 again and repeats a series of processes in order to perform the withdrawal process after selecting the next target digit DG.

  If a negative result is obtained in step SP50, this means that all of the change amount CH has been withdrawn, and at this time, the change control unit 221 moves to the next step SP52.

  In step SP52, the change control unit 221 ends the coin withdrawal subroutine SRT3 and returns the process to the original change withdrawal processing procedure RT1 (FIG. 5).

  As described above, the change control unit 221 sets the target digit DG for each digit when the number of digits is large, and sets the target digit DG as a target digit DG when the number of digits is small. A coin of only DG is withdrawn at a time, and the number of the target digit DG in the change display column CC is enlarged and displayed.

[3-2. Change withdrawal sequence]
Next, the relationship between the withdrawal process from the change processing unit 3, the display of the change display column CC, and the refund to the customer by the cashier will be described with reference to the sequence chart of FIG. 15 corresponding to FIG. Here, as an example, it is assumed that the change amount CH is “3911 yen”.

  The change processing unit 3 first sets the number of denominations based on the change amount CH as “three 1000-yen bills, one 500-yen coin, four 100-yen coins, one 10-yen coin, and 1 yen coin is decided ". Further, the change processing unit 3 displays the change amount CH in the change display column CC with a normal number (black), and sets the initial value of the remaining amount to “3911 yen” which is the same as the change amount CH.

  And since the change amount CH is 1000 yen or more in the sequence Q31, the change processing unit 3 causes the withdrawal unit 19 to withdraw three 1000 yen bills according to the 1000 yen digit of the change amount CH, and the remaining amount Is updated to “911 yen”. At this time, in the change display column CC, the display content is not particularly changed while all digits are displayed as normal numbers.

  In response to this, the cashier gives a refund of 3000 yen taken out from the banknote deposit / withdrawal port 18 while explaining, for example, “I will return 3000 yen from the largest one”.

  Next, in the sequence Q32, the change processing unit 3 calculates the provisional number DM as the provisional target digit DM, which is the largest digit of the remaining amount "911 yen", and calculates the provisional number as five. Therefore, the temporary target digit DM is selected as the target digit DG as it is.

  Then, the change processing unit 3 expands the number of the 100-digit digit, which is the target digit DG, of the change amount CH displayed in the change display column CC, and is a denomination corresponding to the target digit DG “500 yen. Withdraw one ball and four 100 yen coins from the withdrawal unit 17 and update the remaining amount to “11 yen”.

  In response to this, the cashier refers to the 100-yen digit displayed in the change display column CC in an enlarged manner and explains, for example, “I will give you 900 yen next”. Refund the 900 yen taken out from the customer.

  When the change processing unit 3 detects that the coin has been taken out from the coin dispensing port 16 by the sensor 16S, the change processing unit 3 proceeds to the next sequence Q33.

  In sequence Q <b> 33, the change processing unit 3 calculates the provisional number as one by setting the 10-digit digit, which is the largest digit among the remaining amounts of “11 yen”, as the provisional target digit DM. Subsequently, the change processing unit 3 adds the 1-digit digit, which is the next digit, to the temporary target digit DM because the temporary number is less than the threshold value of 5, and thereby the temporary target digit DM is the entire remaining amount. Since it corresponds to a digit, the provisional target digit DM composed of a 10 yen digit and a 1 yen digit is selected as the target digit DG as it is.

  Then, the change processing unit 3 returns the 100-digit digit, which is the immediately preceding target digit DG, of the change amount CH displayed in the change display column CC to the normal size, and is the current target digit DG 10. Enlarge the digits of the yen and the digits of one yen. At the same time, the change processing unit 3 causes the money type corresponding to the target digit DG to be withdrawn from the withdrawal unit 17 such as “one 10-yen coin and one 1-yen coin” and updates the remaining amount to “0 yen”. .

  In response to this, the cashier refers to the 10-yen and 1-yen digits displayed in the change display column CC in an enlarged manner and explains, for example, “I will return the remaining 11 yen”. 11 yen taken out from the coin outlet 16 is refunded to the customer.

  Incidentally, since the change amount is "0 yen", the change processing unit 3 ends the series of withdrawal processing by this sequence Q33.

[3-3. Operation and effect]
In the above configuration, when the change control unit 221 according to the third embodiment receives a change amount CH notification from the overall control unit 5, the change amount CH is displayed in the change display column CC and the change amount CH The number of banknotes and coins to be withdrawn is determined for each denomination. If the change amount CH is 1000 yen or more, the change control unit 221 first withdraws banknotes and updates the remaining amount.

  Subsequently, the change control unit 221 selects the temporary target digit DM, and adds the temporary target digit DM one digit at a time until the temporary number becomes equal to or greater than a threshold value (for example, five), thereby adding one or more target digits. Select DG.

  And the change control part 221 expands and displays the number of the said target digit DG among the change amount CH currently displayed on the change display column CC, and also withdraws the coin of only the money type of the target digit DG.

  In other words, the change control unit 221 confirms the denomination and the number of coins withdrawn by dispensing with the adjacent digits for the digits with a small number of coins to be withdrawn. The required time can be shortened and the time and effort can be reduced within an easy range.

  On the other hand, the change control unit 221 allows cashiers and customers to easily check the denomination and number of coins by withdrawing each digit of a digit with a large number of coins to be withdrawn. it can.

  That is, the change control unit 221 determines for each digit whether to withdraw each digit or to collect a plurality of digits at a time. Therefore, the cashier controls the type and number of coins to be withdrawn at a time. While reducing the burden of confirmation by customers and customers, the required time and effort can be minimized.

  Furthermore, the change control unit 221 enlarges and displays the number of the target digit DG in the change amount CH displayed in the change display column CC in any case. It is possible to easily recognize which part is withdrawn.

  With respect to other points as well, the change control unit 221 can achieve the same operational effects as the change control unit 21 according to the first embodiment.

  According to the above configuration, the change control unit 221 uses one or more digits as the target digit DG according to the number of coins to be withdrawn for each digit, and the change displayed in the change display column CC. In the amount CH, the number of the target digit DG is enlarged and displayed, and the coin of only the denomination of the target digit DG is withdrawn. Thereby, the change control unit 221 can suppress both the type and the number of coins to be dispensed to the coin dispensing port 16 at a time while temporarily changing and emphasizing the display of the change display column CC. Since it is possible to withdraw multiple digits for digits with a small number of sheets, cashiers and customers can easily see the type and number of coins withdrawn for each target digit DG, and a change display field Among the numbers displayed on the CC, it is possible to easily collate with the portion of the target digit DG, and it is possible to reduce the required time and labor.

[4. Fourth Embodiment]
In the fourth embodiment, a change control unit 321 is used instead of the change control unit 21 according to the first embodiment.

[4-1. Change payment processing]
The change control unit 321 switches whether to withdraw all the digits or collect all the digits at once according to the operation of the cashier, particularly when coins are withdrawn from the change. Has been made.

  Specifically, the change control unit 321 has the same circuit configuration as the change control unit 21 according to the first embodiment (FIG. 2), but when the change dispensing program is executed, Differently, a functional block as shown in FIG. 16 is configured by assigning the same reference numerals to those corresponding to FIG.

  That is, the change control unit 321 corresponds to the digit selection unit 42 and the display control unit 44 according to the first embodiment, in addition to the number determination unit 41 and the withdrawal instruction unit 43 similar to those of the first embodiment. A digit selection unit 342 and a display control unit 344 are provided.

  As shown in FIG. 17A, the display control unit 344 displays the change amount CH in the change display column CC in the display screen in the same manner as the display control unit 44, and moves the cursor directly above the number of the target digit DG. CUR is displayed.

  The digit selection unit 342 has two types of withdrawal modes: a withdrawal mode for each digit for selecting the remaining amount as the target digit DG for each digit, and a collective withdrawal mode for selecting all the digits as the target digit DG in a lump. Have. The digit selection unit 342 alternately switches between these withdrawal modes each time a withdrawal mode switching button (not shown) provided on the operation unit 13 (FIG. 1) is pressed.

  Further, the display control unit 344 displays a mode display field MD for displaying the current withdrawal mode in the vicinity of the change display field CC in the display unit 6A. If the current withdrawal mode is the digit-by-digit withdrawal mode, the display control unit 344 displays “every digit” in the mode display field MD as shown in FIG. For example, as shown in FIG. 17B, “collective” is displayed in the mode display field MD.

  Furthermore, when a next digit withdrawal button (not shown) provided on the operation unit 13 is pressed by a cashier, the digit selection unit 342 acquires a next digit withdrawal signal supplied from the operation unit 13. Has been made.

  The change control unit 321 dispenses change according to the change dispensing process procedure RT1 (FIG. 5) as in the first embodiment, but the coin dispensing process at step SP9 corresponds to FIG. A coin dispensing subroutine SRT4 shown in FIG. 18 is executed.

  That is, the change control unit 321 starts the coin withdrawal subroutine SRT4 and proceeds to step SP61, detects whether the current withdrawal mode is the digit-by-digit withdrawal mode or the batch withdrawal mode, and performs the next step. Move to SP62.

  In step SP62, the change control unit 321 determines whether or not it is the digit-by-digit dispensing mode. If a negative result is obtained here, this means that the collective withdrawal mode is selected by the cashier operation, and at this time, the change control unit 321 proceeds to the next step SP63.

  In step SP63, the change control unit 321 uses the digit selection unit 342 to select all digits (up to three digits) corresponding to the remaining amount as the target digit DG, and proceeds to the next step SP64.

  In step SP64, the change control unit 321 causes the display control unit 344 to display a cursor CUR above each number of the target digit DG in the change amount CH displayed in the change display column CC in the display screen (FIG. 17). (B)), the process proceeds to the next step SP65.

  In step SP65, the change control unit 321 generates a withdrawal instruction for dispensing the coins of the target digit DG, that is, all the remaining coins, by the withdrawal instruction unit 43, and supplies the withdrawal instruction to the withdrawal unit 17 to the next. The process proceeds to step SP66.

  In response to this, the withdrawal unit 17 dispenses the coin of the target digit DG to the coin dispensing port 16 (FIG. 1) in accordance with the withdrawal instruction. At this time, the cashier takes out the coins withdrawn from the coin dispensing slot 16 while referring to the change display column CC of the display unit 6A, and returns it to the customer.

  In step SP66, the change control unit 321 updates the remaining amount to “0” by subtracting the amount of money paid out from the remaining amount, and proceeds to the next step SP33.

  On the other hand, if an affirmative result is obtained in step SP62, this means that the digit-by-digit dispensing mode is selected by the cashier operation, and at this time, the change control unit 321 moves to the next step SP67.

  In step SP67, the change control unit 321 uses the digit selection unit 342 to select the maximum digit of the remaining amount as the target digit DG, and notifies the withdrawal instruction unit 43 and the display control unit 344 of the selected digit, and next step SP68. Move on.

  In step SP68, the change control unit 321 causes the display control unit 344 to display the cursor CUR above the number of the target digit DG in the change amount CH displayed in the change display column CC in the display screen (FIG. 17 ( A)), the process proceeds to the next step SP69.

  In step SP69, the change control unit 321 uses the withdrawal instruction unit 43 to generate a withdrawal instruction for dispensing only the coins of the target digit DG, supplies this to the withdrawal unit 17, and then proceeds to the next step SP70. .

  In response to this, the withdrawal unit 17 dispenses only the coins of the target digit DG to the coin withdrawal port 16 (FIG. 1) in accordance with the withdrawal instruction. At this time, the cashier takes out the coins withdrawn from the coin dispensing slot 16 while referring to the change display column CC of the display unit 6A, and returns it to the customer.

  In step SP70, the change control unit 321 updates the remaining amount by subtracting the amount of money already withdrawn from the remaining amount, and proceeds to the next step SP71.

  In step SP71, the change control unit 321 uses the digit selection unit 342 to determine whether the remaining amount is greater than 0, that is, whether there is a coin that has not yet been withdrawn from the change. If a positive result is obtained here, the change control unit 321 proceeds to the next step SP72.

  In step SP72, the change control unit 321 determines whether or not the next digit withdrawal button of the operation unit 13 has been pressed based on whether or not a next digit withdrawal signal has been acquired. If a negative result is obtained here, this means that the cashier is in the process of handing over the change that has been withdrawn to the customer, and the cashier is not ready to take out the next digit change. At this time, the change control unit 321 repeats step SP72 to wait for the next digit withdrawal button to be pressed.

  On the other hand, if an affirmative result is obtained in step SP72, this indicates that the cashier has pressed the next digit withdrawal button by his / her own intention and is ready to take out the next digit change. At this time, the change control unit 321 returns to step SP67 again to repeat the series of processes in order to perform the withdrawal process after selecting the next target digit DG.

  If a negative result is obtained in step SP71, this means that all of the change amount CH has been withdrawn, and at this time, the change control unit 321 moves to the next step SP73.

  In step SP73, the change control unit 321 ends the coin withdrawal subroutine SRT4 and returns the process to the original change withdrawal processing procedure RT1 (FIG. 5).

  As described above, the change control unit 321 follows the withdrawal mode set in accordance with the operation of the cashier, and in the collective withdrawal mode, all the digits of the coins are dispensed in a lump. In the same manner as in the first embodiment, switching is made so as to withdraw one digit at a time, and the display of the target digit DG in the change display column CC is reversed.

[4-2. Operation and effect]
In the above configuration, when the change control unit 321 according to the fourth embodiment receives the change amount CH notification from the overall control unit 5, the change amount CH is displayed in the change display column CC and the change amount CH The number of banknotes and coins to be withdrawn is determined for each denomination. Moreover, if the change amount CH is 1000 yen or more, the change control unit 321 first withdraws banknotes and updates the remaining amount.

  Subsequently, the change control unit 321 detects the withdrawal mode selected by the cashier, and in the collective withdrawal mode, displays all digits corresponding to the remaining amount as the target digits DG in the change display column CC. The cursor CUR is displayed above each number of the target digit DG in the change amount CH that is present, and the coins of the target digit DG, that is, all the remaining coins are withdrawn in a lump.

  If the change control unit 321 is in the digit-by-digit dispensing mode, the change amount displayed in the change display column CC is set to the maximum digit of the remaining amount DG as in the first embodiment. The cursor CUR is displayed on the upper side of the number of the target digit DG in CH, and the coin of only the denomination of the target digit DG is withdrawn.

  For this reason, the change control unit 321 reduces the required time and labor by making a withdrawal in a lump sum, for example, when the cashier is busy or when the total amount of change CH is small. For example, if the customer is a child or an elderly person, he / she can withdraw money by dividing the money into digits and knowing that the required time will be extended or increased. Each time, the denomination and number of coins can be easily confirmed.

  Furthermore, the change control unit 321 displays the cursor CUR above the number of the target digit DG in the change amount CH displayed in the change display column CC in any case. It is possible to easily recognize which part of the amount is withdrawn.

  Further, the change control unit 321 displays the withdrawal mode in the mode display field MD provided in the vicinity of the change display field CC, so that the cashier CH and the target digit are displayed when the cashier checks the change display field CC. In addition to DG, the withdrawal mode at this time can also be confirmed.

  With respect to other points as well, the change control unit 321 can achieve the same effects as the change control unit 21 according to the first embodiment.

  According to the above configuration, the change control unit 321 sets all digits or one digit of the remaining amount as the target digit DG according to the withdrawal mode selected by the cashier, and the change amount CH displayed in the change display column CC. The cursor CUR is displayed on the upper side of the number of the target digit DG, and coins of only the denomination of the target digit DG are withdrawn. Accordingly, the change control unit 321 temporarily changes and emphasizes the display of the change display column CC, and when the digit-by-digit dispensing mode is selected, the coins to be dispensed to the coin dispensing port 16 at a time are selected. Both the type and number of coins can be kept low, and when the batch withdrawal mode is selected, withdrawals can be made in a lump sum, so the type and number of coins withdrawn to cashiers and customers. Can be easily recognized for each target digit DG, and can be easily compared with the portion of the target digit DG among the numbers displayed in the change display column CC. Can also be reduced.
